design Philosophy
SPEED
Matches competitive 100cc gas kart pace with instant electric torque.
This keeps the package fast, light, and maximizes battery duration. Our competitors try and target shifter kart speeds. That appeals to only a small percentage of the karting community and forces compromises with weight, battery duration, and cost.
entry cost
The same price as a new, well-built 100cc motor
We have worked very hard to source high quality, cost effective components. Leveraging recent technical advantages and by building our batteries in-house the cost of our package significantly lower than other kits on the market without compromising performance.
BATTERY RENTAL
Pay per session and skip the $2,000+ upfront battery purchase cost.
With the SIN(E) package, you do not need to purchase a battery with the kit. The battery and charger are the most expensive piece of any electric kit. Instead, battery rental is available per session, matching the running costs of fuel and oil mix in a 2-cycle kart.
Sin(e) Electric Advantage
Technology keeps moving forward. Don't get left behind.

Important Product Disclosures
Regional Availability & Eligibility: This electric motor kit is currently available for purchase exclusively by racers operating at the Utah Motorsports Campus (UMC).
Battery & Charging Infrastructure: The propulsion kit does not include a battery or charger, and these components are not available for individual purchase at this time. Power is supplied via our dedicated battery rental program, available at a rate of $20 per battery.
Data Access & Development: To assist in ongoing product development and to ensure a fair, level playing field across the grid, SINE Propulsion Systems reserves the right to request and review kart performance data from users at any time.
Hardware & Software Updates: As a developmental product, we may periodically require modifications, replacements, or updates to the kit's hardware or software components to improve reliability and performance. All minor updates and refinements will be provided completely free of charge.
By launching SIN(0), we are embarking on a developmental journey, and as an early adopter you are stepping into the role of an essential test driver. While the technology is cutting-edge, it is still evolving; because of this, our team will be trackside at every UMCKC event to provide hands-on technical support, troubleshoot issues, and fine-tune performance in real time. We view this as a true partnership—we are in this together to refine, perfect, and ultimately scale this product for nationwide racing. Your feedback, insights, and track data are incredibly valuable, and we strongly encourage open communication as we work side-by-side to shape the future of karting.
